Signed-off-by: Amos Benari <abenari@redhat.com>

muved the check all to the top of the list and the multiple selection action to the action bar.

fixed colors and order of serias in show host page resources chart refs

fixes #285 - Use Charting system which can work offline

• dashboard charts
• statistics page
• host show page

additionally, main menu buttons and bookmarks drop down are easier to handle and read

fixes #815 - Redirect to login page when editing multiple hosts

this patch converts the mulitple selections to be pure javascript,
removing the buggy AJAX implementation.

fixes #847 - Retrieve last report information per host via the api

this adds two URLS to the API:

/hosts/fqdn/reports/last
/reports/last

both supports JSON output which provides all of the report information.

fixes #806 - Switch to JQuery instead of Prototype JavaScript library

Fixes #609 - Orchestrate puppetca operations

This also includes adding support for a puppet smart-proxy target type
and providing migration support

views cleanup and added more operatingsystems icons

Fixes #453 - Restrict dropdowns based upon user permissions

fixes #601 - virtual machine guest values go away after a validation error

Fixes #366 - Redmine authorization port

This is a major feature which provides RBAC authorization within Foreman
a mental note to myself - never ever work on large commits

Fixes #288 - Moved DashboardController actions (except for #index) to HostsController.

Minor SQL optimization to hosts page

Fixes #179 - allow mass assignment of parameters and host groups.
Greatly inspired by Ashay Humane <ashay.humane@gmail.com> at 5c2e395c

• Remove active scaffold from hosts controller.
• changed default host graphs from one day for up to one week
• added dynamic dropdown boxes for host creation / edit page (e.g. for puppet classes, operating systems etc)....

refs #186 - minor optimization and avoid a problem when there is no
report in the DB while the host last report date exists

fixes #186 - When reports are kept in the database and not deleted/purged the Host.reports.last query starts slowing down and the hosts index page can take minutes to load depending on the number of hosts. By changing Host.reports.last to Host.find(host.id).reports.maximum('id') we make a more efficient query to the database cutting the lookup time.

fixes #151 - add show host page
Added a nested link to hosts to lots of controllers

fixes #129 - Link from hostname on the hosts page is absolute instead of relative (breaking https)

fixes #76 - Foreman creates a link to a report even if the report is already deleted

fixes #50, now reports time is shown as long as there was atleast one report

fixes #38

wrong condition - fixes #34

fixes #34

• Adds a link from host report to host edit
• Resized edit text box size

Fixes #16, this adds the possibility to see the host report status out of the host list

fixes #18: Incorrect link to host editing

Fixes #9 and introduce a basic reporting viewing over http

the hostname is now a link to the edit method

added some status icons, and a bit of DRY

a simple host status indicator

add minimal description to forms

using machine localtime to calculate the time ago

show last compile in time ago

empty tests and controller for now
